Balázs Nagy received the PhD degree

Balázs Nagy defended his doctoral thesis and obtained the Doctor of the Philosophy (PhD) degree.

Csaba Benedek was a keynote speaker at ROBOVIS'20

A keynote lecture about multi-sensorial environment perception has been given at the International Conference on Robotics, Computer Vision and Intelligent Systems (ROBOVIS), by Csaba Benedek.

The lecture gave an overview of the latest results of the MPLab Research Group on Geo-Information Computing, where the main target is to fuse the actual measurements of the newest available sensors used by self-driving vehicles and various sorts of data stored in the latest GIS architectures, enabling real time provision of detailed environmental data for autonomous navigation, offering new extended services for the vehicles' passengers, while city administrations get new tools for efficient and economic maintenance of the GIS databases.

The presenter introduced new scientific results in three main topics, which were accomplished in cooperation with his Ph.D. students, Balázs Nagy and Örkény Zováthi:

  • automtatic transformation of mobile laser scanning (MLS) based point clouds to 3D maps,
  • utilization of high definition 3D maps to support perception and localization based on on-board measurements
  • automatic target-less calibration of Lidar and camera sensors, which is a crucial step for sensor fusion

Lidar demo in the Automotive Hungary 2017 exhibition and in the researcher's night public day

The real time person tracking demo using Velodyne VLP16 sensor was demonstrated in Researcher's night 2017 open day on 29 Sept 2017 in MTA SZTAKI, and in the Automotive Hungary 2017 Exhibition at Hungexpo between 18 and 20 October 2017.

Live Lidar demonstration in the Frankfurt Motor Show

The Lidar data processing solution developed in the GeoComp team was invited by Velodyne Europe executive director Erich Smidt for a live demonstration in the exhibition area of the market leading sensor manufacturing company at the Frankfurt Motor Show 2017 (

The Geocomp team of MPLab had the opportunity at the end of this summer to try the prototype of the newest sensor of Velodyne, called VLP32C which was directly developed for automotive applications. Following quick software development, two solutions of the group received invitation to the IAA Show of Velodyne in middle September.  

On one hand, the SZTAKI software plays an „eye-catcher” role at the exhibition. The program analyses in real time the measurements of a sensor placed at Velodyne’s exhibition area: it separates and tracks the visitors, while the result of processing appears immediately as colored point cloud on a display. On the other hand, the software can also load measurement sequences obtained by a car-mounted Lidar platform for offline data analysis, with automatically extracting the roads and building facade regions, detecting and tracking the moving vehicles and other objects.

As Velodyne announced at the press day of the Motor Show, VLP-32C will act as a critical sensor during their new strategic partnership with Mercedes-Benz.

The research team was represented by Balázs Nagy at the exhibition.

On the cover page of IEEE GRSL

The recent article of the GeoComp research group landed on the cover page of the July 2017 issue of IEEE Geoscience and Remote Sensing Letters.
In the paper, Attila Börcs, Balázs Nagy and Csaba Benedek propose a new approach for object classification in continuously streamed Lidar point clouds collected from urban areas, aiming to extract all vehicles and pedestrians in the neighborhood of the moving sensor. The authors present a complete pipeline for processing the raw Lidar measurement flow, including road-obstacle separation, object extraction and object recognition using a deep learning approach. At the end, the algorithms are tested and evaluated with real measurements collected from various dense urban regions. (23.06.2017)
